Short answer: Yes
Longer answer: You don't increase your iq by being on chess.com forum.
Hi Christopher!
I recently had the same question. Please see my discussion for in depth, intellectual look at this exact question.
https://www.chess.com/forum/view/general/how-much-smarter-are-chess-players-than-the-average-human
Im wondering if its possible to increase ones I.Q. through Chess and of so to what extent. Bobby Fischer was said to have an I.Q. of 187 which is considered a high level genius although there's the question of the chicken and the egg. Was it Chess that made Bobby Fischer so smart or was Bobby Fischer super smart to begin with which is why he was so good at Chess?
